Diễn đàn hỗ trợ Firefox

i have checked my mouse settings and reset everything but no change,,this started after a windows update, so i went in and uninstalled the update but did not fix the problem..i don't know how better to explain it, the scroll just stopped working while trying to scroll web pages,when i try to scroll the page doesn't move ., if i move my pointer over to the right side where the indicator of where you have scrolled to is and i click under it to scroll down and sometimes it kindof goes crazy and scrolls through many,many pages instantly...i hope all this some sense to you computer gurus cause i have tried everything that i know...thanks for giving it a shot..i use firefox browser and windows 11

Every thing will be working fine? And then I click on something, and it takes a long time. And then at the top of my prompt, it says Mozilla firefox is not responding. I've been dealing with this for some time now. You can't figure it out. This is happening on my computer. Also I would update it the program and the very next day.There's a prompt asking me to upload again. I upgrade, and then I still get the same thing.Mazilla is not responding.

I'm having an issue where when you try to do things in-browser, Firefox freezes, puts up a grey screen and holds this way for a few seconds. Scrolling and video seem to trigger it most often. Repeatability is nominal; sometimes I have no problem, sometimes every action I try to take results in another fit of grey screens and freezing.

I'm using version 153.0.3 64bit on Windows 10.

Hello Im using multiple firefox edition on my PC from beta dev to nightly, and recently in nightly and only nightly I've spotted strange issue that appears as window in window screenshot attached, outer x to close or maximize window does not work only the inner and mostly goes after F11 full screen and then return to normal. Troubleshoot mode and restart does not change or fix this.

I've just opened one simple Web site (in addition to Mozilla), and already CPU usage sits at about 20%! Please refer to my recent posts here at "Why is Firefox Suddenly Taking Over my CPU?" for the problem description. I'm re-posting simply in hopes that I can "send data" on this one from outside my sandbox. Regards -- jclarkw

Hello,

I’m experiencing a serious issue after updating Firefox to version 150. Since the update, Firefox frequently freezes and crashes, making it almost impossible to work normally.

My laptop has 16 GB of RAM, and I’m using Windows 10. When I check Task Manager, I can see that Firefox’s memory usage suddenly increases to around 7–8 GB, then drops back down to around 3–4 GB. The memory usage keeps fluctuating heavily.

Also, the number of Firefox processes/tabs in Task Manager keeps increasing, and eventually the browser becomes completely unresponsive.

Could you please investigate this issue and let me know how it can be fixed?

Thank you.

Since a while, I think it is since I created an extra testprofile with "firefox-esr -P", but I've set my main profile as default again

When opening a link in another program than firefox I get always: a popup "Close Firefox" "Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."

I do have both firefox and firefox esr, I usually use regular firefox the second came with the debian 13 repository.

I keep the esr to test display issues for reproducibility on my personal desktop, because I manage debian 13 kiosk-style desktops with firefox-esr.

(I noticed also that the regular firefox profiles can not be opened in firefox esr, so I use an extra profile for esr)

I booted the computer this AM and firefox is acting up. I can go to my email accounts (2), but I can't open an email. Both act like this. They will open with MS Edge and all other functions seem to work on the computer except for firefox.

I tried searching for a solution using duckduckgo and google, many of the links wouldn't open and some that did, just loaded re-loaded, but never finished. Pulldown menus, where they ask a question and click to see the anwer, don't work. They are frozen. Can see the cursor highlight the menus, however it will not allow any interaction with them.

I restarted the computer, there was an update, and I had it update. No change with firefox. I reinstalled firefox. No change. For the moment, I'm out of ideas. Anyone have any thoguhts about this, please help. Thanks in advance. Ken

Everything is gone from the browser today. There is no content in the menu at the top right, except for keyboard shortcuts. When I type in the search bar, nothing happens, and clicking the + to open a new tab does nothing either. My account is still showing at the top, I am signed in and the profile looks fine. I can't "refresh" the browser from the menu, as that is not an option.

UPDATE: FIXED - Today, April 13 - everything is back - I guess Firefox fixed itself.

Whenever I start my machine, without opening Firefox, Ctrl-Shift-I works (For inverting selections in certain programs, for example).

However, once I open Firefox, these 3 keys no longer work when used together (but work in any other combo).

This persists even when I close Firefox, or kill it in Task manager.

Any ideas?

Cheers

My Dell Precision Laptop from 2019 runs a frequently updated Ubuntu 24.04. About one or two weeks ago, after one of the latest Firefox updates, i noticed that video streaming produces rectangular flickering in rapid sweeps. ( Also fast scrolling large text websites produces similar flickering, I think I would have noticed it before...) . If you detected it once, you see it always again... :-( First I fiddled around with the nvidia settings because the driver was also recently updated, without much success. Playing locally stored videos, e.g. with VLC media player, still works fine, so the nvidia driver is not the problem i think. Yesterday I installed Chromium and the video performance is fine! As good as with firefox some weeks ago! So it must be one of the latest updates, that causes the problem. Generally I like firefox more than chromium. I like the control you have, e.g. via Add ons.. So I hope that the firefox performance will increase again... Thank you for firefox! Florian Mengedoht

I've just now noticed that whenever I open the website hxxps://www.hex-rays.com it will hang without finishing loading for a couple of seconds, then the entire browser will freeze. I've already tried on a new profile, verified that no addons or plugins are installed there, and no DLLs hooked into the process. This happens on my physical PC and in an (almost unused) VM, with an ancient version 134.0 and the latest 149.0.

Can anyone else replicate this? Should I create a bug report?

I've been using Tabliss on Firefox without any issues, but immediately after updating to Firefox 151.0, a frustrating new loading delay started happening.

Prior to the update, new tabs loaded instantly. Now, whenever I open a new tab, the page sits on a completely blank screen for about 2 seconds before the Tabliss layout, background image, and widgets finally pop in.

Because this issue did not exist at all before version 151.0, it seems like the latest browser update changed how extension-based new tabs are cached or initialized, causing a new rendering bottleneck.
